Author	Takakusagi S,Takagi H,Yokoyama Y,Kizawa K,Marubashi K,Kosone T,Nagashima S,Takahashi M,Murata K,Okamoto H
Evidence	Her HBV genome was typed as subgenotype B1 and possessed a frameshift mutation due to an insertion of T after nucleotide (nt) 1817 and G to A mutations at nt 1896 and nt 1899 (G1896A/G1899A) in the precore region as well as serine to glutamine substitution of amino acid 21 in the core protein
